Company for question : Differ.Chat (online messaging app)

Can you help me with:

Product design and business model

How can Differ.Chat improve the user experience and impact, and how can they improve the commercial success of the company (e.g., offer a different pilot program, new pricing, advertising model, different payment collection model, etc.).

8. Pricing

What is the optimal way to charge for a solution like Differ.Chat? Should it be a fixed price campus license or a different model would work better (e.g, student-pay, advertising), and corresponds well with the marketing strategy suggested earlier.

9. Retention

As with many consumer applications, retention is a major challenge. How can Differ.Chat improve retention of its students?

Evaluation Rubrics 7 - The recommendations are clearly articulated, are viable, and are supported by convincing arguments; the proposed product design, pricing, and retention strategies are explained in sufficient detail and supported by convincing arguments and credible sources. 4 - Good suggestions, but not enough detail and weak supporting arguments, some parts are irrelevant or redundant, the formatting is inconsistent 1 - Impossible to figure out what the recommendation is, supporting arguments are absent or completely off the point, not supported by credible sources.
